To all whom it may concern:

A tachments for Phonographs of'which the following, taken in connection with the 210-. companying. drawings, is a full, clear, and

exact description.

' This invention relates to certain improvenients in reproducer attachments for phonographs, and involves the use of a non-metallic needle-supporting extension of the vibratonarm as one feature, and a non'metalllc ring co-axial with and secured to the back of the diaphragm case-carrying a radially projecting eighted arm or bracket for supportingthe non-metallic extension and holding the tracer point in yielding en gage'ment'with theundulations of the record.

The niainobject is to reproduce more accurately and definitely the sound records byeliminating as far as possible the accompanying metallic sounds incidental to the use of relatively long metallic tubes carrying the diaphragm case and needle point, as in the standard makes of machines of the Victrola,Columbia and Edison type. In other Words, I have sought to accomplish these results by locating the reproduoer as closely as possible to the resonator or amplifier and relatively remote from the needle point by interposing arelatively long intermediate non-metallic bar having one end attached to-the vibrator-arm connected to the-diaphragm and its other'end provided with-.a needle holder. f

V The'object of the non-metallic ring on the diaphragm case is to permit the use of a suitable Weighted support for the non-me tallic bar Without liability of transmitting metallic sounds from said support to the diaphragm of the reproducer or to the resonator with which the reproducer communicates.

Another object is to enable this attachment to be used in connection with any of thestandard forms of QProd'ucers.

longitudinal vertical sectional view through A Qther objects and uses relating to specific I parts of the device will be brought out in the following description.

In the drawingsFigure 1 is a top plan of a standard form of reproducer equipped with my improved attachments. Fig. 2 is a side elevation of the same, the dotted lines showing respectively'a portion of a record disk and a portion of the cabinet containing the resonator or amplifier. Fig. 3 is an enlarged the connecting bar between the needle point and reproducer showing the meansfor con-' necting said bar to the vibrator-arm taken on line 3-3, Fig. 1. Fig. 4. is an enlarged vertical sectional. view of the attachment at the back of the reproducer'taken on line -il, Fig. 1, eXcept'that the reproducer is shown in elevation. Fig 5 is a transverse vertical sectional View through the connection between the non-metallic needle bar and its, supporting bracket taken on line 5-5, Fig. 1.

in order that my invention may be clearly understood, I have shown a standard type of reproducer l having the usual diaphragm -2 and an operating lever 3- therefor, the latter being fulcrumed intermediate its ends in suitable bearings 4 on the diaphragm case with one end attached to the diaphragm and its other end flexibly connected by a ball and socket-joint 5 to the adjacent end of a non-metallic extension bar or lever 6 'of Wood or equivalent fibrous material, the opposite end of said bar being enlarged at 7 for receiving a needle holder .8'having a tracer point or needle .9 secured therein by a set screw 10 so as to follow the undulations or sound record of a record disk or cylinder 11.

Secured to the back of the diaphragm case l is a non-metallic ring +12 of 'wood or other fibrous material capable of receiving and supporting a radially projectingarm or bracket -l3 Which is secured at one end to the periphery of the ring -12 and has its other end Weighted by an extra member 14-.and provided with a yoke 15 for receiving and supporting the ad- 100 1 may be brought into close proximity to the entrance tube as 18 of the resonator box within the cabinet A- as the nonm etallic bar 6 is interposed between the reproducer and needle point -9 thus obviating the use of the usual long metallic tube leading from the reproducer to the entrance tube of the resonator, as in the standard types of machines now in use in which the reproducer with a needle point attached thereto is directly over the record. I

In order that the reproducer and attachments-may be free to swing vertically and horizontally a tubular hub 19 is secured to the back of the non-metallic ring l2 and is journaled in a head '20 of a T-shaped pipe 2l-- having its vertical portion journaled in a suitable bearing 23 in the top of the cabinet so as to permit the reproducer with the attachments thereon to rotate in vertical and horizontal planes or rather in. planes at right angles to each other, the hub 19 having a considerable portion of one side thereof cut away at -24 to register with the upright portion of the pipe 21- for permitting the transmission of sound waves from the diaphragm to the resonator with which the lower end of the pipe 18 is connected in any well-known manner not necessary to illustrate or describe. 7

The ball-and-socket joint 5 allows the bar -6 and reproducer 1- to be turned relatively to each other to adapt the needle point -9- to difi'erent makes of phonographs, as for example, the Edison, Columbia and Victrola.- That is, the needle supporting bar 6-+ may be adjusted so that the needle and reproducer will face the record as in the Edison machine, or may, as shown in the drawings, be adjusted so that the needle will extend in a direction parallel to the face of the reproducer, as in the Columbia andFVictrola.

In adapting this reproducer for Edison records, the tube --18- with the reproducer thereon would be withdrawn from the socket in which it is shown and an elbow tube, not shown, placed in the socket in the case --A- with one arm in a substantially horizontal position in which the tube l8-- would. then be inserted so as to bring the face of the reproducer at the under side, under which conditions the pivotal screws 17 for the bar 6- would be loosened to release said bar, which would then be turned a quarter turn to bring-the needle 9- at the under side, whereupon the screws -17 would be re-tightened against the adjacent side of the bar to hold the latter in operative ing shown in Fig. 3, in which the pins are I there shown engaged, it being evident that similar metal bushings could be provided in all four sides of the wood bar to receive the pointed ends of the pins if necessary, but the device is entirely operative if the pins enter the wood, the latter being usually made of maple ,or similar hard wood.

What I claim is:

1. In a phonograph reproducer, aimetal diaphragm-actuating lever and a needle supporting wood extension thereof of greaterlength than the lever, said lever and extension being flexibly connected end to end, and an additional support for the extension intermediate the ends thereof.

2. In a phonograph reproducer, a metal diaphragm-actuating lever, and a needle supporting extension of wood and of greater length than the lever, said lever and exten-- sion being connected end to end by a ball and socket joint, and an additional support for the extension intermediate the ends thereof.

3. In a phonograph reproducer, a metal diaphragm actuating lever and a wood bar having one end connected by a ball and socket joint to one end of the metal lever and its other end provided with a needle holder, and means for pivotally supporting the bar at a point between the ball and socket joint and needle holder- .lOO

' 4. In a phonograph reproducer, a diaphragm-actuating lever, a needle-supporting ar of wood of greater length than the lever and forming an extension thereof, a weighted arm secured to the diaphragm caseand exwith a vibrator-arm, of a non-metallic point supporting extension attached to said arm. a hollow non-metalhc rlng secured to said case to rock therewith, and connections other than the vibrator-arm and case between thering and extension for causing the extension to rock with the case.
